This report presents guidelines to transportation agencies for the management of their assets related to return on investment. The details in the report rely upon the work conducted by the research team and their experiences. It is published alongside a spreadsheet tool which helps agencies evaluate their simulations of return on investment for TAM.

This document provides an explanation of the steps taken to develop the risk register tool. The research team conducted a survey of current practices for risk management across state DOTs, international agencies, and non-transportation organizations. Then they built a draft tool and received user feedback before finalizing the tool.

NCHRP Synthesis 556 summarizes state DOT practices used to identify pavement and bridge asset locations repeatedly damaged by emergency events and to mitigate the risk of recurring damage in those locations. The synthesis focuses particularly on mitigation practices that concurrently advance TAM and TPM objectives. Information for this synthesis was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies.
